Camera Does not Require a Password

[jethornton]

I have a D-Link DSC-5020L camera and it does not require a password. When I try and add it I get this error
cannot concatenate 'str' and 'NoneType' objects

[jethornton]

Oh I forgot to mention it has a user name but no password

[rotrials]

Please try something like:

rtsp://ip:port/Streaming/Channels/101/
or
rtsp://username:password@ip:port/Streaming/Channels/101/

But I think this kind of camera does not support RTSP :(

[jethornton]

And how would that help the actual problem that motioneye tries to concatenate the empty password field?

@jethornton please specify your motionEye version and please attach your motioneye log.

[jethornton]

motionEye Version | 0.39.3
Motion Version | 4.0
OS Version | Debian 9.7
motioneye.log

Thanks for the link to get the motioneye log.

@jethornton do you have your credentials embedded into the URL? If yes, can you please remove them and try again?

[jethornton]

The URL is http://192.168.1.50/video.cgi?resolution=VGA and I put admin in the user box and nothing in the password box because it does not require a password.

Can you open the http://192.168.1.50/video.cgi?resolution=VGA link with your browser and see a valid MJPEG? If yes, can I see a screenshot of it, just to make sure it's indeed a MJPEG stream without any surrounding HTML crap?

[jethornton]

Here you go, I don't have any problem logging into the camera from a web page. The only problem is as above MotionEye fails because the password is empty.

[ccrisan]

I have cameras with empty password and I can't seem to reproduce your error, that's my problem. The stack trace does not show up in your log file.

[jethornton]

Does your camera need a user name but no password? That's what my camera needs. I don't have any problem if I supply no user name and no password or a user name and a password. If I put a user name and no password then the concatenation attempt fails with empty password field.

[ccrisan]

@jethornton I configured one of my cameras to require user and no password, for this specific purpose. I can add it without problem.

Could you please set the log_level to debug, repeat the operation and see what the log has to say?

[jethornton]

This is the only entry in the log after I attempt to add the camera and setting log_level to debug.
